Why is there a color difference in the stainless steel color decorative plate?

It is reported that the titanium plating furnaces in Foshan, Guangdong are basically semi-automatic vacuum titanium plating furnaces. In order to reduce production costs, many manufacturers continuously increase the speed in the production process to achieve higher output; therefore, the film layer becomes thinner and thinner, and the working time of the titanium plating furnace is reduced from the original one hour to 10 minutes or less. . At the same time, because the working time of the titanium plating furnace is too short, the technical requirements of voltage, current, gas uniformity, etc. are correspondingly reduced and unstable, so it is easy to produce a decrease in the bonding force between the color film layer and the stainless steel surface. Undesirable consequences such as uneven color eventually lead to the phenomenon that the stainless steel plate is prone to chromatic aberration, and even the film layer is peeled off. On the other hand, the traditional water-plated stainless steel black titanium plate also lacks current, voltage, and working time. The situation similar to that of vacuum plating will also occur.
  
The thin color film on the surface of the stainless steel color decorative sheet may also cause local, irregular and irregular colors under the chemical reaction caused by temperature, humidity and even contact with general chemical materials after the product is formed or used. Change phenomenon, and its extent and time cannot be predicted.
